Strap for Elegant Collection Automatic 29 Stainless Steel / MOP / Strap

The lug width is precisely 20 mm. This dimension is specifically engineered for the 29 mm case diameter, maintaining elegant proportions on the wrist. Any compatible strap must meet this exact constructive tolerance.

Genuine alligator remains the canonical choice for this watch, thanks to its symmetrical, fine grain that enhances the formal character. Vegetable-tanned calf leather offers softness and evolving patina. For contemporary contexts, shell cordovan represents the most conscious solution, with durability and natural lustre without artificiality.

The Longines Elegant is equipped with a deployante clasp (rectangular folding buckle). Simply open the clasp by pressing the small lateral buttons: no specific tools required. Insert the new 20 mm strap into the case spring bars, close the deployante carefully to avoid scratching the lugs.

Yes, provided it is 20 mm lug width. Quality aftermarket straps in alligator, calf, or shell cordovan maintain mechanical compatibility with the original deployante. Always verify the measurement is precise: tolerances within 0.5 mm can cause friction in the passants or unwanted gaps.

With daily use and standard maintenance (hydration every six months, protection from stagnant water), a vegetable-tanned calf or alligator strap lasts 2–3 years before replacement is needed. Shell cordovan, due to fibre density, can reach 4–5 years. Longevity depends on UV exposure, ambient humidity, and frequency of wear.
